HORIBA Jobin Yvon leads the commercial holographic diffraction grating technology. For example: the concave aberration corrected holographic grating (CACHG), innovated by HORIBA Jobin Yvon, combines a simplicity, consistency, throughput, and image quality not possible with other optical designs. OEMs recognize the advantages, replacing multi-element optical systems with our one-piece CACHG. The performance gains, manufacturing ease, and improvements in long-term quality make high volume instrumentation cost effective.
